Commander 31 Bianca

Designed by the renowned Danish duo Knud E. Hansen and Jan Kjærulff, this classic 1970s cruiser represents solid Scandinavian yacht design principles during sailing's golden era. Built by Bianca Yachts from 1969 to 1976, the Commander 31 combines moderate proportions with seaworthy characteristics that made it appealing to cruising sailors of the period. The boat's traditional fin keel with rudder on skeg configuration provides directional stability and easier steering, particularly valued for longer passages. With a displacement of 7,715 pounds and substantial ballast ratio, she offers the steady, predictable motion preferred by cruising sailors over racing-oriented designs. The fractional sloop rig keeps sail handling manageable while providing adequate power for coastal and light offshore work. Her 22-foot waterline length and moderate beam create comfortable interior volume without sacrificing sailing characteristics. The comfort ratio of 26.62 suggests pleasant motion in seaway conditions, while the capsize screening value of 1.79 indicates reasonable stability margins for coastal cruising ventures. With 150 hulls produced during her seven-year run, the Commander 31 found favor among sailors seeking reliable, unpretentious cruising boats. Today, these well-built fiberglass classics appeal to sailors appreciating traditional design values and proven seaworthiness for coastal and near-offshore adventures.
